Nico Rosberg has said that Pirelli risked causing the 'biggest shunts ever' with the tyre failures that occurred over the Belgian Grand Prix weekend.
The Mercedes driver was left shaken after a high-speed right rear tyre failure in Friday practice at Spa-Francorchamps, which it is believed was caused by an external source such as debris or a car part.
But what has annoyed Rosberg the most is that Sebastian Vettel also suffered a high-speed blowout on the exit of a high-speed Raidillon in the race.
That incident prompted a furious outburst from the four-time world champion, who said that the situation in F1 was no longer 'safe'.
Rosberg agrees with Vettel that having two high-speed tyre failures the situation was one that should not be tolerated, and changes have to be made for the next race at Monza.
"Vettel blowing up his tyre, that's really not acceptable," Rosberg said in his regular post-race video.
"For either of us - for me on Friday or for him [on Sunday] - if that would have happened a couple of metres earlier or later we would have had huge shunts, I mean the biggest shunts ever, because this track is just so fast.
"The next track is Monza, the fastest track of the year, so they have to think of something to try and improve that situation.
"For example, activating all the rear view cameras so if the teams are watching that they can see before a tyre explodes or something and give us warning, or I don't know something like that."
